Subject: fix($compile): don't touch static element attributes

Compiler should not reassign values to element attributes if its not neccessary due
to interpolation or special attribute magic (ng-src -> src)

This resolves several issues on IE caused by reassigning script.src attribute which
caused all of the scripts to be reloaded.
